`Applicationfiled October 12, 1925. vSerial No. 62,085.

The invention relatesto trolleys suchasy are used in connection withelectric'cars or locomotives. i 1

` The `purposes of the inventionare: To provide a light compact andserviceable trolley which maybe produced at arelatively small cost andwhich shall be flexible and safe in use and in which partssubject towearmay be easily and quickly replaced; -to provide a sleet cutter ofimproved construction in conjunction with theharp of the trolley; and toprovide atroll'eyv embodying service# able-'improvements safe-guardingthe trolley against injury to the electric line onfwhich it operates ortothe 'usual stay wires steading the 'trolley' line. Y f

The present invention is a modification and improvement of the`invention set forth in United States Patent No. 1528372; granted tomeMarch 3rd, 1925; for improvement in trolleys.

The invention consists in'improved structural details shown in theaccompanying drawing, to which reference is hereby made and now to bedescribed and finally recited in the claims.

Figure 1 is a side` elevation of a complete trolleyv embodying myinvention; Fig. 2 1s a top planv of the `same trolley; F ig.- 3 is ahorizontal section taken on the line 3 3 o-f Fig.' 1; Fig. 4 is avertical transverse section taken on the line @-4 of Fig. 1; Fig. 5 isav verticaly section through the trolley taken on the line 5-5 of Fig.2; 6 is a perspective view of the detached sleet cutter viewed frombelow; and Fig. 7 is a 'vertical section on the line 7 7 of 6. Similarreference numerals and characters refer to similar parts throughout alltheviews.` 1 l YIhave found by experiment that the trol-` ley shown anddescribed in my .said applica-v tion is subject to the objection thatthe metallic contacts therein shown and -described are insufcient toeffectively control the flow of the electric current rwhere Vhightension is used. I have also found by experimentV that the Yconstructionshown anddescr-ibedin my saidpatent is such that excessive rotation ofthe shoeis likely to occur, thereby placing the shoe in .such positionthat-there'is danger of the; shoe engagingon the stay wires of theytrolley line; 'often result-ingin breaking .the

stay wires and other injury to the trolley line.v rlfhe main purpose ofthe `present invention is to obviate these objections.

' I wiil'lrst describe in detail the mechanh cal features `whichVcharacterize the present invention yand will recite-'in the appendedclaims' the improvements herein set forth.

Theharp 6 is a. casting having integral upwardly extending 77 adjacentto the forward end ofthe shoe;

the harp'has also in its upper part a` de-.

pression 8 inl which *the forward part of.` the shoe 9 is located; and adepression 10 in which` a contact'spring 12'is located. Thespr'ing 12engages with the under side of for a large One terminal part of thespring 12 is secured in the depression 10 by a rivet 19.A j

The shoe 9 and its spindle 13 are of manganese steel, or other hardmetal, smoothly finished and polishedjto run on the transmission linewithout the line. The harp and appurtenances will lpreferably be made ofan alloy. The harp has also a lengthwise chamber `15 containing twinfiat springs 16 whichjbear on Hat parts 14' of the spindle 13.. One endof each of the springs 15 is secured by a rivet 17 which through thebodv ofthe harp and extends.

undue wear or abrasion of through'both springs. The free terminals ofthe springs l16 bear on the inner sidewalls of the harp.

' The spindle 13 has flat parts 14C on' which the springs 16l engage insuch manner that rotation of the stem serves to stress they springsoppositely and both springs act torestore the shoe to normalpositionafterit has l been rotated more or less.r

Aiiat Contact spring 18 similar to the spring A 12 is secured Von Vtheunder side of the harp by a rivet 20. 'Each of the springs 12 and 18 hasa transverse hole in lwhich thelspindle 13 ro-' tates freely. A nut 22screwsonto thelower terminal part .of the stem'and is `secured byvatransverse cotter pin 23.`

VVhenthe parts are assembled as shownV in Figs. 1 and 2, the forward endof the shoe will be in" the depression 8 and the `members7 within' thedepression; will preventv such eX-y cessive movement as might bring theforward party of 'the shoe intosuch 'position' that 'it f rlhe 'shoe 9has a lengthwise groove might engage with the stay wires of thetrolleyline.

2.1 `the upper surfaceof'which, atfthe front' E end of the shoe.; is'approximately in the plane oftheV inclined; part 25 of the harp, inorder that the line-Wire will lie naturally inthe groove of the harpVvvithout danger of4 abrasien of the-wire by rthe front of the shoe;

10uY l l` whilepermitting free` oscillation of the shoe" Y Thedoublecontacts l2 and 1 8 have sufficient surface to safel conduct hightension current. The form o the groove 21 permits the shoe 9 to travelsafely on the wire and to oscillate sufficiently to permit theV trolleyto run safely around all usual curves in the line.;

and the members 7 prevent excessive and dangerous oscillation' of theshoe.

The sleet cutter is a casting, preferably of manganesejbronze or otherobdurate wear-resisting-metal and comprises a body- 2G, lengthwiseprongs 27 integral with the body and spaced apart from each other theproper distance to permit the prongs to st-raddle the harp body, oneprong on each side.

Aligned-holes 28 in the respective prongs receive .a removable pin `29which extends ha@` transverse hole'SO (Fig. 5)?in the har ` slime Body26 has` an integral downwardly throu pl odgv and connects the sleetcutter with ar Y o inclined membeiwlshaped to fit in the groove 214ofthe shoe9..` f

The'purposes ofthe member 31 are tosupportfthe cutter structure inanupwardly` and rearwardly inclined position onthe shoe and to` form agood electrical contact ofthe cutter arcuate groove .32 to `guidethewith the shoe;

.Whenthe parts` are assembled thev upperV edges of the prongs 27 engageon the laterally extending members-p7 of the harp and tend to keep thememberl' in close electricalcontact withlthe shoe9. i

The cutter body 26has atits free end an l` travel" of the cutter body onthe line wire. Theinclined sidewalls of the groove 32 converge to forma: sleetcutting edge 33 (Fig. 7) whichlbears against the under side ofthe line wire and cuts the sleet as the cutter travels along the wire.The `upper end of the sleet cutter extends upwardly above the rear partofthe shoe in order e that the sleet, as it is stripped from the linewirewill=fall clear of the harp thus avoiding excessive arcing. e i y eThe sleet cutter will be used only when there isrsleet on thelinewire.V

To detach the sleet cutter from the harp, the

i bolt 29 will be 'withdrawn and the cutter will be lifted off the harp,andmay` be easily. and quickly replaced'when needed. Y y

The operation of the trolley will be read-` z ily:` understood fromtheforegoing descrip.

' tion. l

I am aware ofthe prior' usejofsprings in; a lengthwise chamber oftheharp to restore the j shoe to straight-forward position after itfhas .ibeen oscillated. Iam also aware that contact springs haverbeen usedbetweenran oscillating shoeand the body of the harp.- I-therefore donotclaimbroadly the use of springs admitting of oscillation of theshoe. Idohow-` ever, believe that 1 am iirstto devise and use stationary means on`the harp limiting `the scopeof oscillationof-the forward part of ytheshoe; and that I am the firstto deviseand use a shoe having alengthwise'groovelthe bottom of which,'at the forward end of the shoe,is approximately in the; lane of the inclined uppervsurface oftheb 'gyof the harp.
